MACHlNtI FOR FOLDING AND PASTING THE ENDS OF PAPER COLLARS.

SPECIFICATION formingpart of Letters Patent No. 258,711, dated May 30, 1882.

Application filed February 14, 1882. (No model.)

To all whom it may concern:

Be it known that I, EDGAR GARY, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Machines for Folding and Pasting the Ends of Paper Collars and other Artieles,of which the following is aspecification.

The object of this invention is to provide a machine in which the collars or articles to be folded and-pasted are placed on endless belts or chains and carried over paste-disks and through the folding mechanism into a drying apparatus. This object I accomplish by the construction and arrangement of mechanism illustrated in the accompanyingdrawings, in which- Figure l is a section of my machine in the plane at m, Fig. 2. Fig. 2 is a plan view. Figs. 3, 4, and 5 are details.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the frame, on the upper ends of which are mounted the shafts a a, carrying the rolls 1) I), over which pass the endless chains or belts c,which constitute the feed mechanism. These belts or chains, whose upper surfaces run flush with the table 0, have a series of small lugs, pro jecting upward,secured to them,so that when a collar is laid on the table 0 of the machine these lugs catch it and feed it along over the paste-disks and into thefolding device.

The paste-disks d, Figs. 1 and 3, have the usual form with paste surface just large enough to supply the necessary quantity of paste to the inner surface of the collar, timed so as to put the paste in the proper place and receive their supply from paste-distributing roller 6, which runs in the paste-trough f. The distributing-rollerereceives its motion through a belt, 9, running over a pulley, h, mounted on the counter-shaft t, which has its bearings in the frame A. This counter-shaft has motion imparted to it by means of a belt, j, which connects itwith the shaft to.

A belt or chain, Z, which runs over the center of the roll 1), Figs. 1 and 2, imparts motion to the folder-shaft m, on which are mounted the folder-cams it. These cams, which are situated one at each end of the folder-shaft m, are of the shape shown in Fig. 3, and are timed to the motion of the chains or belts 0, so that each half-revolution ot' the folder-shaft m the projecting parts 0 of the folding-cams a will bend down that partot' the collar that is to be folded in preparatory to passing through the sheet-metal folder p, which completes the fold. The form of this folder is shown in Figs.3 and 4, and it is situated just beyond the foldershaft 022. a

The collar-blank B, when it is placed on the machine, is ofthe form shown in Fig. 5. The flaps 11 while the collar-blank is being carried along by the belts or chains 0 and without arrestingits motion, are first bent down atright angles by the folder-cams a, after which it is carried through the sheet-metal folder p,wherc the fold is completed and the flap is bent under, as shown in dotted lines in Fig.5.

The paste-disks d are secured to a shaft, 01, which has its hearings in the frame A, and is geared to the folder-shaftm by gear-wheels (1 d so that the paste-disk d and the foldencams u always work together, being so adjusted that when the paste-disks have coated the flaps that are next to be folded, and as the collars are brought under the folder-cams, the latter strike the flaps and fold the|n,as above described. Over the paste-disksd, but not so as to touch them or to come in contact with the paste on them, are situated small friction-rollers q,which press on the flaps I) of the collar B as it is being coated with paste by the paste-disks d. These rollers turn on studs projecting from small angle-pieces, which are secured tothe guides r. These guides 1', which consist offlat pieces of metal, are raised sufficiently from the table 0' to permit the collars to pass under them, and are intended to keep the ends of the collars down on the chains or bolts 0 as the collars pass through the pasting and foldingdevices. 8 s s are similar guides to keep the center of the collar down on the table 0.

The friction-rollers q and the paste-disks d are so placed in relation to each other that, while the paste-disks revolve continuously, the friction-rollers turn only while a collar-flap is being coated with paste,when the collar-flaps, as they are being carried along by the chains or belts c, fill the space between thepaste-disks d and the friction-rollers q, causing the latter to turn, thereby fulfilling their purpose of keeping the collar-flap in contact with the paste-disks only while it is being coated with paste, and then with the least possible friction.

WhatI claim as new, and desire to secure by Letters Patent, is

1. In a machine for folding and pasting collars, the combination, substantially as described, of the transverse shaft on, provided near each end with a folder-cam, n, with the carrying belts or chains moving at right air gles to said shaft.

2. In a machine for folding and pasting collure, the combination of the guides r, carrying rotary friction-rollers q, with the pasting-disks d, arranged directly beneath the friction-rollers, the carrying belts or chains, and thetransverse shaft m, provided near each end with a folder-cam, a, substantially as described.

3. The combination of the transverse foldershaft m, carrying near each end a folder-cam, 9:,the transverse shaft d,carrying paste-disks d and geared at one end with the folder-shaft, and the friction-rollers q, arranged directly above the paste-disks, substantially as described.

In testimony whereofl have hereunto set my hand and seal in the presence of two subscribing witnesses.
